More about this tool

Binary encode/decode converts UTF-8 text to binary representation of bytes and back.

Useful for learning, debugging low-level data, protocols, logs, and dev tasks. Configure bit grouping, separators, and preview byte values when decoding binary strings back to UTF-8 text.

Invalid binary input should show clear errors instead of wrong output.

Frequently Asked Questions

What is binary encoding?

Binary encoding represents bytes as binary digits. Each byte is usually written as 8 bits of zeros and ones.

How does text become binary?

Text is first encoded to UTF-8 bytes, then each byte is converted to 8 bits.

Why does Unicode text use more bytes?

In UTF-8, many non-ASCII characters use more than one byte, so one character may become several 8-bit groups.

Can binary with spaces be decoded?

Yes. The tool can ignore spaces, tabs, and line breaks when decoding if the corresponding setting is enabled.

Why must bit count be a multiple of 8?

One byte is 8 bits. To rebuild bytes, the binary string after removing separators must split into groups of 8 bits.

What if binary does not decode to text?

The bytes may not be valid UTF-8 text. Use Bytes preview mode to inspect bytes as decimal, hex, and ASCII.

Is binary encoding encryption?

No. Binary encoding is only another representation of bytes, not protection.

How is binary different from hex?

Binary shows each byte as 8 bits. Hex shows each byte as two hexadecimal characters and is often easier to read in logs.

Is my data sent to the server?

No. Processing runs locally in your browser and data is not sent to the server.

Do I need to register?

No. The tool works without registration.
